Dated market lookup

Find what bitcoin was worth on any past date

Choose a date and amount to compare a historical BTC/USD close with the latest cached reference. Venue, candle time and data coverage stay visible.

Selected date versus latest reference

A daily close is one venue observation, not one universal Bitcoin price.

A historical price needs a timestamp and venue

Bitcoin trades around the clock. “The price on a date” normally means a selected market’s daily close, not every trade made that day. Different exchanges can use different candle boundaries and briefly show different prices.

Nearest observation rule

If the chosen date has no candle in the cached series, the tool returns the nearest available observation and prints its actual date. It never silently invents a missing close.

Questions this calculator cannot answer

  • What price a person actually paid after spread and fees.
  • Whether an exchange order would have filled at the close.
  • Taxes, custody charges or lost access.
  • What Bitcoin will be worth later.

Nominal dollars are not purchasing power

A dollar amount from years ago and the same number today do not buy the same basket of goods. Use the macro overlay for inflation context without claiming that correlation proves cause.

Method and boundary

How the historical comparison is assembled

The tool keeps the requested date, actual observation, source market, and latest reference as separate facts.

01

Find the observation

The lookup selects the nearest available daily BTC/USD close and displays the date that was actually returned.

02

Translate the amount

The entered dollar amount is divided by that historical close to model the BTC represented at the time.

03

Mark the endpoint

That BTC amount is multiplied by the latest reference. Spread, fees, tax, custody, and inflation remain outside the comparison.

Historical-price questions the chart cannot settle alone

Which Bitcoin price is used?

The result names its BTC/USD venue and returns the nearest cached daily close. Bitcoin has no central closing auction, so another venue or timestamp may differ.

Why is my requested date different?

The source may lack a candle for that exact date or the cached archive may start later. The tool prints both the requested date and the observation it actually used.

Does the return include fees or inflation?

No. It compares nominal reference prices. It excludes trading costs, custody, taxes, failed execution and changes in the purchasing power of dollars.

Dated market lookup

Look up a historical Bitcoin price with its conditions attached

The tool returns the daily close nearest the date you choose from a five-year BTC/USD series, then compares it with the current reference. A historical price is an observation from one market on one day, and the tool says which.

  1. Part 1

    A daily close is one number for a day of trading

    Bitcoin trades continuously, so the close is the last observation in a UTC day. The same date had a high and a low, sometimes far apart, and a purchase at noon in New York used a different price.

    • The date shown is the observation used, which may differ from the date requested at weekends or gaps.
    • Coverage is the series start and end; earlier dates are not extrapolated.
    • The market is named beside the value.

  2. Part 2

    Do not use it as a tax basis

    Tax authorities accept a reasonable, consistently applied source, but they expect the record you actually relied on. Use the tool to sanity-check, then keep the exchange statement or the published rate you file with.

    • Keep the purchase confirmation with its own timestamp.
    • Convert to local currency with the rate on the same day.
    • Apply the same method to every lot.
